Abstract

La présente invention a pour objet un Procédé de décontamination de déchets radioactifs alcalins boratés comprenant au moins un composé organique et un radioélément pour obtenir un concentrat de déchets décontaminés et des déchets secondaires (W5.1), le procédé comprenant au moins une étape de préparation des déchets, une étape (1) de minéralisation des composés organiques contenus dans les déchets, une étape d'extraction des radioéléments contenus dans les déchets pour obtenir le concentrat de déchets décontaminés. L'étape d'extraction comprend une étape de contact des déchets avec du charbon actif.The present invention relates to a method for decontaminating borated alkaline radioactive waste comprising at least one organic compound and a radioelement to obtain a concentrate of decontaminated waste and secondary waste (W5.1), the process comprising at least one preparation step waste, a step (1) of mineralization of the organic compounds contained in the waste, a step of extraction of the radioelements contained in the waste to obtain the concentrate of decontaminated waste. The extraction step includes a step of contacting the waste with activated carbon.
